Trends in the Incidence of Sudden Unexpected Infant Death in the Newborn: 1995–2014.
The definition of SUID covers:
SUID occurs most frequently between one and four months. When SUID occurs within the first six days of life, it is known as Sudden Unexpected Postnatal Collapse (SUPS). In 1992, the American Academy of Pediatrics (AAP) published guidelines for healthy sleeping. In the years that followed, a 25% increase in SIDS was observed during the first month of life. The authors of the study presume that some of the fatal cases previously diagnosed as SIDS have now been divided into different categories (ASSB, ‘death from an unknown cause’ or SUPC). In order to explain this possibility, the authors investigated each SUID case, covering all categories including SUPC. This was an attempt to detect patterns which could explain the increase.
In the study, all forms of SUID were compared with the birth/death report in the CDC WONDER online database (1995–2014). This concerned both SUID in neonatal infants (younger than 28 days) and the post-neonatal phase (28–364 days). The annual incidence of SUID in 100,000 births between 1995 and 2014 and the percentage of each SUID due to unsafe sleeping conditions (MSBC – Mechanical Suffocation Bed or Cradle) and ASSB were listed separately for both the neonatal and post-neonatal periods. Furthermore, data was compiled for the number of deaths in the first few hours, in hours one to twenty-three and in days one to six.
